Rfid shuffler system for game pieces

ABSTRACT

The present invention relates to a RFID shuffler system in which a radio frequency identification (RFID) is associated with each game piece. The game pieces can be, for example, revealer devices, cards, and dice or Mah Jongg tiles. A random number generator selects an identification value and sends an activation signal to the RFID tag of the game piece matching the identification value. For example, a RFID reader can read the RFID tag including the selected identification value. After the activation signal is received at the RFID tag of the game piece, the game piece can be activated, for example, by having activation of an associated light or activation of a vibration or sound. Alternatively, a housing or game board can activate received game pieces for selection of the game pieces.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a device for a game in which game pieces are randomly shuffled by randomly activating a radio frequency identification tag (RFID) associated with the game piece or activating a game device receiving a game piece.

2. Description of Related Art

Conventional card shuffling devices are known. U.S. Pat. No. 6,299,167 describes a playing card shuffler for shuffling a stack of playing cards with random distribution. An infeed playing card stack holder supports an unshuffled playing card stack and discharges playing cards from incremental positions of the unshuffled playing card stack to a shuffled card receiver.

U.S. Pat. No. 6,889,979 disclose a card shuffler with a drivable shuffling storage means which is provided with compartments for receiving cards and which is associated with an input apparatus for inserting cards into the compartments one by one and an output storage means which is spaced from the same for the shuffled cards, with the drive of the shuffling storage means, the input apparatus and the output storage means being controlled by an electronic control system. The card shuffler is capable of continually displaying the number of playing cards situated in the card shuffler and thus of providing the operator with the opportunity to have at all times certainty about the complete number of playing cards by an input apparatus being provided with a draw-in zone whose height corresponds substantially to the thickness of a card and a first detection means and a second detection means is provided which detects the cards inserted into and removed from the shuffling storage means.

It is desirable to provide a simple device for randomly shuffling game pieces or cards.

SUMMARY OF THE INVENTION

The present invention relates to a RFID shuffler system in which a radio frequency identification (RFID) is associated with each game piece. The game pieces can be, for example, revealer devices, cards, and dice or Mah Jongg tiles. A random number generator selects an identification value and sends an activation signal to the RFID tag of the game piece matching the identification value. For example, a RFID reader can read the RFID tag including the selected identification value. After the activation signal is received at the RFID tag of the game piece, the game piece can be activated, for example, by having activation of an associated light or activation of a vibration or sound. In one embodiment, the game pieces can be held in a housing moved by a mechanical arm to appear to be shuffling the game pieces.
